A billion is a thousand-million.
Metric Units:
Deca - Ten
Hecto - Hundred
Kilo - Thousand
Mega - Million
Giga - Billion
Tera - Trillion
Many of the prefixes are uncommonly used. But, say, for example you had a billion grams (gigagram) and you wanted to convert it to megagrams, you would multiply it by 1000. So... one gigagram would be 1000 megagrams.
Now, it gets a little more complicated when one talks about computers.
Computers are based on factors of 2.
210 = 1024 which is the "standard" base for many computer calculations, especially those using metric prefixes.
So, a kilobyte would be 1024 bytes.
a megabyte is 1024 kilobytes, or 1024*1024 bytes = 1,048,576 bytes
a gigabyte is 1024 megabytes, or 1024*1024*1024 bytes = 1,073,741,824 bytes.
a terabyte is 1024 gigabytes, or 1024*1024*1024*1024 bytes = 1,099,511,627,776 bytes.
multiply billion by 1000 to get million for example 10 billion = 10000 million
In the common manner that billion is used, a billion is 1,000 million. In order to convert billion into millions, multiply by 1,000
that's like 40000 million
There are 1,000 millions (m) in a billion ( b). So 2.624b = 2,624 million.
Divide by 1000.
multiply billion by 1000 to get million for example 10 billion = 10000 million
305 million = 0.305 billion
470.5 billion = 470500 million.
6,521 million
1 billion = 1000 million. So 3.2 billion = 1000*.2 = 3200 million. Simple!
1000 million = 1 billion so 101 million = 101/1000 = 0.101 billion. Simple!

There are 1,000 millions (m) in a billion ( b). So 2.624b = 2,624 million.
29,000 million
2100 million
Divide by 1000.
